Why Warranty Knowledge Matters
Congratulations on your new construction home in the Houston area. Whether you are in a new community in Katy, Cypress, Brookshire, or Conroe, understanding your HVAC warranty coverage is crucial to protecting your investment and ensuring years of comfortable living.
Most new homeowners receive warranty documents at closing but never fully understand what is covered, for how long, and what steps they need to take to maintain coverage. A missed registration deadline can cut your warranty in half. A skipped maintenance appointment can void it entirely. This guide walks you through everything you need to know.
Types of HVAC Warranties
Your new construction HVAC system comes with multiple layers of warranty protection. Understanding each type helps you know who to call when issues arise and ensures you do not accidentally void your coverage.
Installation & Workmanship
- Duration: Typically 1–2 years from closing
- Covers: Installation defects, ductwork, wiring, system balancing, airflow issues
- Who to call: Your builder or their warranty company
- Response time: Usually 24–48 hours for HVAC issues
Equipment & Components
- Duration: 5–10 years (varies by component)
- Covers: Compressor, heat exchanger, all other parts
- Who to call: Licensed HVAC contractor
- Registration: Often required within 90 days
Critical Timing Issue
Many manufacturer warranties require registration within 90 days of installation. Missing this deadline can reduce your coverage from 10 years to just 5 years on major components like the compressor. Your builder should handle registration — but always verify it happened and keep the confirmation.
Builder vs Manufacturer: What Each Covers
Builder Warranty Coverage
Your builder's warranty covers the installation and integration of your HVAC system with your home. This includes proper sizing and load calculations, ductwork installation and sealing, thermostat wiring and programming, system balancing and airflow, and integration with your home's electrical and gas systems.
The builder warranty is your primary protection during the first 1–2 years. If your system was improperly sized, if duct connections are leaking into the attic, or if the refrigerant charge was off from the initial install — these are builder warranty issues. Document them before the clock runs out.
Manufacturer Warranty Coverage
The equipment manufacturer — brands like Carrier, Trane, Lennox, or Rheem — warrants the actual HVAC components. Compressors typically carry 10-year coverage. Heat exchangers get 5–10 years. All other parts are usually covered for 5 years. Labor coverage varies and is often only 1–2 years.
The manufacturer warranty outlasts the builder warranty by years. Once the builder warranty expires, the manufacturer warranty is your only remaining protection — and it only stays valid if you have maintained the system properly and kept records.
Texas HB 2110: Automatic Warranty Transfer
Texas House Bill 2110, effective September 1, 2021, provides important protection for homeowners regarding HVAC warranty transfers. This law is particularly relevant if you sell your home before the manufacturer warranty expires.
What HB 2110 Does
The law mandates that manufacturer warranties for air conditioning systems automatically transfer to new homeowners when the property is sold, as long as the HVAC system conveys with the home as a fixture. No paperwork required. No transfer fees. Coverage continues seamlessly for the remaining warranty period.
Why This Matters
Before HB 2110, many manufacturers required explicit warranty transfer paperwork — and some charged fees for it. Missed transfers meant buyers inherited a system with no warranty coverage, even if years of coverage remained. The law eliminated that risk entirely.
For you as a homeowner, this means your remaining HVAC warranty is a genuine selling point when you list your home. A buyer inheriting 7 years of compressor warranty coverage has real value — and they get it automatically under Texas law.
How to Protect Your Coverage
During the Builder Warranty Period
Your builder warranty is a narrow window — usually 12 months from closing. Everything you document during this period becomes a record. Everything you miss becomes your problem after month 13.
- Document everything: Keep photos and written records of any HVAC issues, no matter how small
- Use the builder's process: Going outside their warranty network may void coverage
- Report issues promptly: Do not wait until month 11 to file your first warranty claim
- Test both modes: Run heating and cooling before the warranty expires — not just whichever season you are in
Maintenance Requirements
Both builder and manufacturer warranties require proper maintenance. This is not a suggestion — it is a contractual requirement. Failure to maintain your system can void coverage entirely, leaving you with a $10,000+ equipment replacement on your own dime.
Change Air Filters
Every 1–3 months, more frequently in Houston's dusty new construction suburbs. A dirty filter is the number one cause of warranty-voiding maintenance issues. Check monthly during peak summer.
Clear the Outdoor Unit
Keep 2 feet of clearance around the condenser. Prairie lots collect construction debris, tumbleweeds, and grass clippings that restrict airflow and force the compressor to work harder.
Annual Professional Service
Schedule professional maintenance at least once per year. Keep the receipt. This is the single most important thing you can do to maintain warranty validity — and the one most homeowners skip.
Keep Records
Save every service receipt, filter purchase, and maintenance record. If you ever need to file a warranty claim, documentation is the difference between approval and denial.
Houston Climate Consideration
Houston's humid climate and the constant construction activity in growing suburbs like Cypress and Katy means your filters work harder than average. During peak summer months, check filters monthly and replace as needed. A clogged filter in July does not just reduce comfort — it strains the compressor and creates the kind of failure that manufacturers can attribute to neglect.
Common Warranty Mistakes
These are the mistakes we see most often in new construction homes across the Houston metro. Every one of them is avoidable.
Not Verifying Manufacturer Registration
Many homeowners assume their builder registered the equipment warranty. Builders handle hundreds of closings — things get missed. Always verify registration yourself and keep confirmation documents. A 5-minute check can save you 5 years of coverage.
DIY Repairs During Warranty Period
Any work performed by unlicensed individuals can void both builder and manufacturer warranties. Even tasks that seem simple — replacing a thermostat, adding refrigerant, cleaning coils — should be done by licensed professionals while the system is under warranty.
Skipping Annual Maintenance
Missing annual professional maintenance is the fastest way to void warranty coverage. Budget $150–300 annually for professional service. It is an investment that protects a $10,000+ asset.
Not Understanding Coverage Periods
Different components have different warranty periods. The compressor may be covered for 10 years while labor is only covered for 1. Keep a calendar noting when various coverages expire so you can schedule an inspection before critical deadlines pass.
Poor Documentation
When issues arise, take photos, keep written records, and save all correspondence. A warranty claim without documentation is a denied warranty claim. Treat every HVAC issue like it might end up in a dispute — because some of them will.
Your Warranty Protection Checklist
Secure Your Coverage
Verify manufacturer warranty registration. Create digital copies of all warranty documents. Schedule your first maintenance appointment. Test the system in both heating and cooling modes. Document any initial issues and report them to your builder immediately.
Pre-Expiration Inspection
Schedule a professional Performance Check before your builder's one-year warranty expires. This inspection documents any installation defects, sizing issues, duct leaks, or refrigerant charge problems while the builder is still responsible for fixing them. This is the single most valuable appointment in your first year of ownership.
Maintain Coverage
Check and change air filters regularly — monthly during Houston summers. Keep the outdoor unit clean and unobstructed. Monitor energy bills for unusual increases. Schedule annual professional maintenance and keep all service records organized. Use only licensed HVAC contractors for any work on the system.
Document and Report
Document the problem with photos and a written description. Contact your builder first if you are still within the builder warranty period. Use only licensed contractors for any repairs. Keep all receipts and service documentation. Follow up in writing on every warranty claim — phone calls are not records.
Frequently Asked Questions
Can I use any HVAC contractor for warranty work?
During the builder warranty period, you should use the builder's preferred contractor to avoid disputes over coverage. After the builder warranty expires, any licensed HVAC contractor can perform warranty work under the manufacturer warranty — but keep records of their license number and all work performed.
What happens if my builder goes out of business?
Your manufacturer warranty survives independently of your builder. Even if the builder closes, the equipment manufacturer is still obligated to honor the warranty terms. Your builder warranty, however, may be backed by a third-party warranty company — check your closing documents to find out who that is and whether they are still operating.
Does a home warranty plan replace my HVAC warranties?
No. A home warranty plan (like American Home Shield or First American) is a separate service contract. It does not replace your builder or manufacturer warranty. During your warranty period, always file claims through the original warranty first — home warranty plans should be a backup, not a primary.
How do I find out who manufactured my HVAC system?
Check the label on your outdoor condensing unit and indoor air handler. The manufacturer name, model number, and serial number are printed on a metal plate or sticker. You will need this information for warranty registration verification and for filing any future claims.
